Question

# The integrated rate equation for first-order reaction is $$A$$ $$\rightarrow$$ products.

A
K=2.303tlog[A]0[A]t
B
K=1tln[A]t[A]0
C
K=2.303tlog10[A]t[A]0
D
K=1tln[A]t[A]0

Solution

## The correct option is A $$K=\displaystyle\frac{2.303}{t}log\frac{[A]_0}{[A]_t}$$For the first reaction, $$A$$ $$\rightarrow$$ Products, the integrated rate law is given by the equation.$$K=\displaystyle\frac{2.303}{t}log\frac{[A]_0}{[A]_t}$$where, $$[A]_0$$ is the initial concentration of the reactant at $$t=0$$$$[A]_t$$ is the concentration of the reactant at t $$=$$ t.So, the correct option is $$A$$.Chemistry
